veyer frame forms an enlarged hopper 22 at the receiving end of saidconveyer which is beneath the overhanging discharge end of saidelevating conveyer and is arranged to clear the under and rearward sidesof the rearward projections of the upright side frame members I5, I5 topermit pivotal movement of said conveyers with respect to each other.

Referring now in particular to the novel construction of the hopper atthe receiving end of the conveyer I2 and the arrangement whereby itsdepth opposite the discharge point of said elevating conveyer may bemaintained as the conveyers are pivotally moved with respect to eachother without increasing the distance between the conveyers in avertical direction, side walls 23, and 24 are pivoted to the forwardportion of the flared retaining wall 2| of the hopper 22 adjacentopposite sides of the conveyer. Said side walls are each of a similarconstruction and conform generally to the form of said ilared retainingwall and extend rearwardly therealong from their point of pivotalconnection thereto. As herein shown, each of said side walls ispivotally mounted on said outwardly flared retainingwall by means of anut and bolt 25 to permit independent pivotal movement of said sidewalls in an upward or downward direction in planes parallel to theplanes of the flared retaining wall 2|.

The side wall 23 is guided intermediate its ends in a pair of parallelspaced guide brackets 26, 26 secured to the sides I9 of said conveyerand extending angularly outwardly therefrom in parallel relationshipwith respect to the retaining wall 2| while the side wall 24 is guidedin a similar guide bracket 2T. The rearward ends of the side walls 23and 24 are each guided in a guide formed by guide strips 28, 28. Each ofsaid guide strips is secured to an opposite side of the side wall 2| andspaced therefrom in parallel relation with respect thereto to form aguide extending parallel to said side Wall.

Means are provided to hold eachof said side Walls in an upwardlyextended position with respect to said hopper which comprises tensionsprings 29, 29. As herein shown, one'spring 29 isv connected to aprojection 30 extending outwardly from an outwardly flared side 20 andat its opposite end to a projection 3| extending outwardly from thebottom of the side wall 23 adjacent the rearward end thereof. YThe otherspring 29 is interposed between a hook 32 projecting outwardly from theupper end of the guide strip 28 and a projection 33 projecting from thelower side of said side Wall.

It willrbe apparent from the foregoing that when one conveyer or theother is pivotally moved in a'horizontal direction a certainpredetermined distance that an under side 34 of one upright side framemember I5 will' engage the top of one of the side walls 23 or 24depending upon'the direction of movement of the conveyer for depressingthe respective side wall to permit free turning movement of saidconveyers with respect to each other. Thus during such turning movementthe side wall opposite the depressed side wall will be in an upwardlyextended position which will retain the depth of the hopper opposite thedischarge point of said discharge conveyer and thus permit saidconveyers to be disposed closely adjacent each other without sacriiicingdepth of said hopper and without increasing the vertical dimensions ofthe machine.

While I have herein shown and described one form in whichmy inventionmay be embodied, it will be understood that the construction thereof andthe arrangement of the various parts may be altered without departingfrom the spirit and scope thereof. Furthermore, I do not wish to beconstrued as limiting myself to the specific embodiment illustrated,excepting as it may be limited in the appended claims.

I claim as my invention:

5. In a conveying mechanism, two conveyers having their adjacent ends incascade relationship, the receiving conveyer having upwardly extendingwalls forming a hopper, the discharge conveyer being mounted forlateralpivotal movement toward oppositesides of said hopper, and yieldableextensions on the sides of said hopper walls depressible by engagementwith the discharge conveyer when the latter is swung to one side or theother of said hopperV comprising side Y walls pivotally mounted adjacentopposite sides of the forward end of said hopper and extending upwardlyanderearwardly therealong for independent yieldable movement withrespect thereto. 6. In a conveying mechanism, two conveyers having theiradjacent' ends incascade relationship, the receiving conveyer havingupwardly extending walls forming a hopper, the dischargeconveyerbeingmounted f or lateral pivotal movement, towardopposite sidesof said hopper, and yieldable extensions on the sides of said hopperwalls depressible by engagement with the discharge conveyer when thelatter is swung to one side or the other of said hopper comprising sideY Walls pivotally mounted adjacent opposite sides of the forward end ofsaid hopper and extending upwardly and rearwardly therealong forindependentyieldable movement with respect thereto, and tension meansfor independently holding said side walls in an upwardly extendedposition with respect to said hopper.

7. In a conveying mechanism, two conveyers one of which is mounted forlateral pivotal movement about an axis disposed within limits of theother, one of said conveyers having a discharge end overhanging areceiving end of said other` conveyer, said receiving end havingupwardly extending side walls forming a hopper, and side wall extensionsextending along the sides of said hopper walls depressible by engagementwith the discharge conveyer when the latter is swung to one side or theother of said hopper.

8. In a conveying mechanism, two conveyers one of which is mounted forlateral pivotal movement about an axis disposed within limits of theother, one of said conveyers having a discharge end overhanging areceiving end of said other conveyer, said receiving end having upwardlyextending side walls forming a hopper, side wall extensions extendingupwardly along the sides of said hopper walls depressible by engagementwith the discharge conveyer when the latter is swung to one side or theother of said hopper, and tension means for independently holding saidside walls in an upwardly extended position with respect to said hopper.

9. In a conveying mechanism, two conveyers, both of which are mountedfor lateral pivotal movement, one of said conveyers having a dischargeend overhanging a receiving end of said other conveyer, said receivingend having upwardly extending walls forming a hopper, and yieldable sidewall extensions extending upwardly along the side of said hopper wallsdepressible by engagement with the discharge conveyer when either ofsaid conveyers is swung to one side or the other.
